Active Recombinant Human IL21R&IL2RG protein, Fc-tagged

• Cat.No.: IL21R&IL2RG-1565H
• Product Overview: Recombinant Human IL21R&IL2RG protein(Cys20-Pro236(IL-21R)&Leu23-Asn254(IL-2Rgamma)), fused with Fc tag, was expressed in HEK293.

Specification

• Source: HEK293
• Species: Human
• Tag: Fc
• Form: Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.
• Bio-activity: Immobilized Human IL-21, Tag Free at 5 μg/mL (100 μL/well) can bind Human IL-21 R & IL-2 R gamma Heterodimer Protein, Fc Tag&Fc Tag with a linear range of 5-78 ng/mL.
• Molecular Mass: The protein has a calculated MW of 51.5 kDa (IL-21 R) & 53.6 kDa (IL-2 R gamma). The protein migrates as 65 kDa and 70 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
